As you may have noticed, Blizzard sent us a request that we remove unreleased information relating to spells and talents in Wrath of the Lich King, and we have chosen to comply with that request. However, obviously that cat is out of the bag (and was before we got there), and if you want to find that information, one good place to look for it is the Wotlk leaks wiki.
From flight paths to pictures to spells and talents (including those for Death Knights) to profession information, that wiki is a great resource for unreleased information. Obviously this is stll alpha information, and everything is unfinished and changeable -- if any of you were playing WoW in alpha or beta, you know how much things changed before release (and after). Still, it's nice to get a glimpse of what's in store.
